When I using SSIS to export data from database.

There are two exception was caught:

The exception detail as below:

SSIS Error Code DTS_E_OLEDB_EXCEL_NOT_SUPPORTED: The Excel Connection Manager is not supported in the 64-bit version of SSIS, as no OLE DB provider is available.

--Solution one--

If you're using the Visual Studio to Debugging that SSIS.

Maybe you can revise the 'Run64Runtime' propertie i.e. select the 'False' option:

 

--Solution--

If you're using a SQL Agent Job to run this SSIS.

If you're using SQL Server 2008, there are shout be a checkbox on the Job Step page to run the package in 32-bit mode.

If you're using SQL Server 2006, you will have to change the Job Step from an Integration Services to an Operating System step, and specify a DTEXEC command line instead. The DTEXEC command line needs to specify the DTEXEC.EXE from the Program File (x86) folders, NOT the DTEXEC.EXE from the Program Files folders.
